Background technology
It is well known that voltage-withstand test refers to the low voltage electrical devices to various electrical equipments, insulating materials and insulation system
Voltage endurance capability is tested.The basic theory of voltage-withstand test is that a product is exposed under the environment of very severe, if
Product can also maintain normal condition under this rugged environment, it is possible to it is determined that worked under normal environment,
Also normal situation can necessarily be maintained.Different products has different technical specifications, is substantially by one in voltage-withstand test
Individual high voltage is added on product and tests, and this voltage has to last for one time of regulation.If a spare part or equipment exist
In the time of regulation, its breakdown current also keeps within the limits prescribed, it is possible to determine this spare part or equipment normal
Under conditions of operate very safe, the point inspection instrument of existing voltage-withstand test does not reach insulation effect, and Detection results a lot
It is bad, operating efficiency is easily influenceed, therefore, invent that a kind of have very much to solve the above problems for the point inspection instrument of voltage-withstand test must
Will.
